I can't speak for earlier in the Afghanistan campaign but certainly in more recent times, Iran has been supporting the Taliban. I doubt it's out of altruism though and more due to the dislike of Western forces and Afghan policy in certain regions (but then, arguably, nothing in the Middle East is done with altruism in mind) .

If you don't like that wait until you find out about the origins of the Taliban and America's support for the precursor Islamist group(s).

Indeed it is, however it’s an informed opinion back up by 2 reputable sources.
Have you got anything to even remotely hint to the contrary? Especially given even the USSC concurs with me on this.

1980s Mujahideen =/= 1990s Taliban.
The Taliban didn't even form until the early 1990s from a faction (of which there was many) of the Mujahideen.

The fact that the only the usual suspects like Pakistan, KSA and the UAE actually recognised the Taliban regime in Afghanistan tells you how much international support they (didn't) have.

Might one enquire why you’re de facto excusing the fact that the taliban were trained and armed, originally, by the west?
To try and lay the blame solely at the feet of Pakistan, ksa et al. Is not only lazy but it is wrong. Especially given that all of the aforementioned states are clients of a certain country and as per the onus on responsibility... well.

It actually seems like you're desperate to blame the rise of Taliban on the West. My argument is that the Taliban didn't even form until after American support to the Mujahideen had ended following the cessation of the Soviet occupation. If you're blaming the US for the Taliban, you may as well blame the Soviets even more so for invading in 1979 and turning the entire nation into a warzone (especially if you're partial to blaming the US for the rise of Daesh - an argument not without merit due to way Iraq was handled post 2003).

It's a far lazier stance to simply assert that the West created the Taliban. The reality isn't anywhere near that clear-cut.
What is clear that nations like Pakistan (especially the ISI which still seems to support the Taliban to this day), the KSA, Qatar etc might want American support but don't particularly want to give anything other than token gestures when it comes to fighting Islamic terrorism in return - especially if they're from the same sect. The fact that Bin Laden lived for years less than a mile away from a Pakistan military academy says much about their attitude to Islamic terrorism.

I'm not saying the US is blameless - it's ironic how the 1990 Iraqi invasion of Kuwait distracted American foreign policy away from Afghanistan after the Soviets left whereas the 2003 invasion of Iraq distracted NATO from sorting out Afghanistan.
